Tenable has announced that its research team has discovered a critical vulnerability in Siemens STEP 7 TIA Portal, design and automation software for industrial control systems (ICS).
The vulnerability, which impacts the same family of devices compromised in the STUXNET attack, could be used as a stepping stone in a tailored attack against critical infrastructure, with the potential for catastrophic damage.
According to Tenable, the flaw [CVE-2019-10915] would allow an unauthenticated, remote attacker to perform any administrative actions on the system, enabling them to add malicious code to adjacent ICS.
With the vulnerability, a bad actor could also exploit the vulnerability to harvest data in order to plan a future, targeted attack. The delicate nature and function of critical infrastructure means
